FAQ

 

Q: Does this tubing come with triclamp ends to be coupled together?
A: This particular tubing comes without tri-clamp ends standard. We can always weld tri-clamp ferrules to the end of tubes for any specific length you need. These products are referred to as tri-clamp spool assemblies. If you need a specific length, please
contact us.
 
Q: Are you able to cut tubing to lengths that don't require freight shipping? Say 5' lengths for example.?
A:Yes, we are able to cut down to other sizes. UPS Ground is able to ship up to 7' without the tubing being considered "oversized".We do charge a cutting fee for this service, however. Please contact us for a quote.
 
Q:How much does 1 stick of 4" tube weigh?
A: One 20' Stick of 4" Sanitary Tubing weighs approximately 75 pounds.
 
Q:You list gauge of this tubing at 16, but the wall thickness at 0.065". Isn't 16 gauge 0.0625"?
A: The wall thickness and gauges are all displayed in the table below. Please contact us if you have any other questions.
 
Q: Do you sell tubing in anything less than cases? I need to order just over 400 feet but don't want to pay for two cases as this is More than I need.
A: We do sell tubing on an individual basis however there is a $50 "broken box" fee applied to any order less than an entire case.Since we don't offer a way to order individual tube pieces online please call us to place an order over the phone.
 
Q: Do this product ship via freight?
A: Yes, our tubing comes in standard 20 foot lengths and will need to ship via freight. I'd also like to mention that there is a broken box charge meaning that if you do not order an entire box of tubing you will be charge additional fees as such. For more information please contact us. Thanks.
